Functions to extract raw simulated samples

Usage

extract_sim(sim)

extract_hr(hr.pi)

extract_km_obs(km.pi)

extract_medsurv(km.pi)

extract_medsurv_delta(km.pi)

Arguments

sim

A survparamsim class object generated by surv_param_sim() function.

hr.pi

a return object from calc_hr_pi() function.

km.pi

A return object from calc_km_pi() function.

Details

extract_sim() extracts raw survival time & event status for all simulated subjects.

extract_hr() extracts simulated HR for all repeated simulations. If HR was calculated based on simulated survival times with calc_hr_pi() function, it also returns p values for Cox regression fits, one for each group based on Wald test and another for the overall significance of the coefficient based on logrank test. The latter has the same values across treatment groups when >2 levels in treatment

extract_km_obs() extracts observed Kaplan-Meier curves.

extract_medsurv() extracts simulated median survival times for all repeated simulations

extract_medsurv_delta() extracts delta of median survival times between treatment groups
